But lawyers for the family dialed back the rhetoric and said they have no reason to distrust the sheriff's office. They just want to find the truth and they realize there's a process involved in that, said Tennessee-based attorney Randy Fishman, who is also Matthew Pollow's uncle.

In a statement issued Thursday, the Palm Beach County Sheriff's Office said Pollow charged at Rosenthal with a screwdriver, adding that the deputy, in fear for his life, fired at Pollow.

Although family members have said Matthew Pollow had "mental issues," they also said they never knew him to be violent or behave aggressively.

Also in the statement that was issued Thursday, it was revealed that both PBSO and Boca Raton police had a number of run-ins with Pollow over the years.
